You really don't want to limit your fat intake during pregnancy.
Here's the diet I have been trying to follow:
Diet for Pregnant and Nursing Mothers
Cod Liver Oil to supply 20,000 IU vitamin A and 2000 IU vitamin D per day
1 quart (or 32 ounces) whole milk daily, preferably raw and from pasture-fed cows (learn more about raw milk on our website, A Campaign for Real Milk,
www.realmilk.com)
4 tablespoons butter daily, preferably from pasture-fed cows
2 or more eggs daily, preferably from pastured chickens
Additional egg yolks daily, added to smoothies, salad dressings, scrambled eggs, etc.
3-4 ounces fresh liver, once or twice per week (If you have been told to avoid liver for fear of getting "too much Vitamin A," be sure to read Vitamin A Saga)
Fresh seafood, 2-4 times per week, particularly wild salmon, shellfish and fish eggs
Fresh beef or lamb daily, always consumed with the fat
Oily fish or lard daily, for vitamin D
2 tablespoons coconut oil daily, used in cooking or smoothies, etc.
Lacto-fermented condiments and beverages
Bone broths used in soups, stews and sauces
Soaked whole grains
Fresh vegetables and fruits
AVOID:
* Trans fatty acids (e.g., hydrogenated oils)
* Junk foods
* Commercial fried foods
* Sugar
* White flour
* Soft drinks
* Caffeine
* Alcohol
* Cigarettes
* Drugs (even prescription drugs)

Don't worry about the "experts" commenting on your weight gain. If you're eating good foods, as you said, just eat.
